Awww yeahh.. I've been able to finally remove after finding this post the following way: sudo find /var/lib/dpkg -exec grep -l "oracle-java7-installer" {} \; showed a bunch of files, I've added exit 0 to first line by typing sudo gedit /var/lib/dpkg/info/oracle-java7-installer.prerm, saved file and closed gedit. Finally, after I was back on command line, typed sudo dpkg -P oracle-java7-installer and it worked.
